UNITED STATES PATENT @rrrcn DAVID F. MCKIM, OF CABLE CITY, MONTANA TERRITORY.

ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 325,429, dated September 1, 1885.

Application filed April 23, 1885.

To aZZ whom it may concern:

Be it known that I, DAVID F. MoKIM, of Cable City, in the county of Deer Lodge and Territory of Montana, have invented a new and Improved Ore-Separator, of which the {ollowing is a full, clear, and exact descrip- My invention relates to ore separators or concentrators, and has for its object to promote more convenient adjustment and steadier working of the ore-receiving belt, and to provide better regulation of the water-supply to the belt, so as to insure the better separation and closer grading of the ores.

The invention consists in the particular constructions and combinations of parts of the oreseparator, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my improved ore-separator, partly broken away and in section. Fig. 2 is a front end view thereof. Fig. 3 is a plan View in section on thelinexw', Fig. 1, and Fig. 4c is a rear end elevation of the machine in vertical section on the line 11 y, Fig. 1.

The letter A indicates the frame of the separator, to the side posts, a a, of which are held by bolts b the bearing-plates B B, and to the opposite side posts, a a, of the frame are held by bolts 0 c the bearing-plates O O. Y

The bearings B are provided with central studs or gndgeons, b c, and opposite end lips,

0 the inner faces of which lips are curved on a radius from the center of studs 1) c, on which and between the lips are fitted loosely the boxes B O, in which are journaled at opposite ends of the machine the main rollers D E, over which runs the endless carrier-belt F, which receives the ore from a feeder, G, at the front end of the machine.

As seen best in Fig. 2, the shaftboxes B G are held to their respective bearings by bolts 1') c, which pass into the bearings through lateral curved slots of the boxes, so that when said bolts are loosened the boxes are free to turn or rock on the axial studs 11 c and between the end lips, 1x 0 of the bearings as the outer ends, (Z c, of the rollers D E are lowered or adjusted to incline that side of the endless (No model.)

carrierbelt F more or less, as required to suit the particular class-of ore being operated upon. To permit the belt F to be so inclined, the bearing-plates O C have vertical slots 0 0*, through which the fastening-bolts c 0 pass into the frame-posts a a, so that the bearings O C may be raised or lowered bodily on the frame posts, which may be done by turning the wheel-nuts H H, which fit screw-threads on hanger-rodsh h, which pass through the top bar of frame A, and are secured to the bearings G O, as shown.

To the four corner bearing-plates, B B G C. are fixed lugs or brackets l, on which rests a frame, I, so as to pass between the opposite sides of the endless belt F, and in frame I are journaled a series of rollers, .I, on which the upper side of the belt F rests as it travels along with the ore-slime, the rollers J keeping the belt from sagging between the rollers D E, so that the water washed over the belt and the ore on it will have the best effect in separating or grading the ore.

Underneath the lower side of belt F, I arrange the rollers K L transversely of the machine, so that the lower side of the belt bears on these rollers. The roller K is journaled in bracket-arms or hangers it is, fixed to the rollerframe I, so as to raise or incline the belt in front of roller E, and cause the ore and water to more easily drop from the belt. The roller L has its end bearings in the side parts, in m, of a yoke or stirrup bar, M, which connected at its ends at m with the lower ends of hangers N,which are guided in or on the side bars of frame A, and receive on their upper ends the wheel-nuts O, which may be turned to raise the yoke M more or less, to cause the roller L to bear with more or less force against the belt F, and to make the belt-tightening action of the roller L more effective I connect to each side mof the yoke M a link, 1?, which is slotted at 12 near its other end, for the pas sage of a screw or bolt, 1), by which the link may be fastened to the frame-posts a o at that end of the machine.

It is evident that by adjusting the wheelnuts 0 and links 1? the roller L may be drawn upward, and also carried toward the main belt-roller D, to tighten the belt F on rollers D E, as may be required from time to time, and as the belt may be inclined more or less in separating different ores, as above described, the ends of the axle of the tighteningroller L may independently be adjusted, so the roller shall always bear fairly across the entire width of the ore-belt F and hold it properly to its work. Separate side hangers with links may be used to support roller L; but the yoke M, as described, is preferred.

The letter It indicates the tailings chute, which is held to the frame A by bracket-arnis a" r, so that its inclined side part passes between t-he opposite sides of the belt.

At S is shown a base-plate or floor,whieh is supported at suitable height above the traveling belt F by brackets or hangers s 8. At the forward end of plate S the ore-feed box G is formed or attached and next to it is the first fixed water-box, T, of about the same length as the ore-box G, and toward the rear of the machine from the water-box T the plate or floor S is fitted with plates or partitions 25, dividing it into three sections or forming three compartments, made successively longer toward the rear end of the machine. By means of capplates i, fixed to partitions t, or otherwise, are formed in or on the plate S suitable slideways or guides,in which the successivelylonger adjustable and inclined water-boxes U V W are fitted; and to the back ends of these boxes are attached the handle bars a '0 w, which pass through the back wall-piece, t fixed to the plate S, and may be bound fast by screws u o w, to hold the boxes U V W so they shall discharge water at any desired places onto the ore-belt F below.

Each of the boxes G U V W is provided with one or more riffles, as at m, to check the currents of ore and water in the usual manner.

Beneath the belt F, at the rear end of the machine, is arranged a water-pipe, X, having suitable perforations through which the water spouts upon the belt, as in Fig. 4, to wash therefrom any ore which may be carried around the roller K by the belt; and below the pipe X are arranged the boxes or receptacles Y for the different grades of ore, the boxes being formed by fitting partitions yinto a trough or box, Y, which has a forward-inclined extension reaching beyond the roller K, so as to catch all the falling ore and avoid waste of it.

At Z is shown a pulley, which is fast on the shaft of roller D, and which receives abelt for operating the machine by any convenient motor.

As the machine is operated the ore discharged from the box G onto the belt F is subjected to four separate washings as it is carried toward boxes Y by water running from any conveniently-arranged pipes into the waterboxes T U V W, and thence to the belt, and by shifting the movable water-boxes U V W and regulating the supply of water thereto the ores will be washed so as to grade them closely, the heavier and more valuable ores remaining next the upper or high edge of the belt, and the lighter and less valuable ore particles being carried farther over toward the tailings-box It, into which the comparatively worthless ore particles fall, and from which they may be conducted for subsequent treatment, if preferred, while the valuable graded ores are carried over by the belt F and fall or are washed off into their respective boxes Y at the end of the machine.

It is evident that the arrangement of the boxes for the belt-roller shafts in the bearingplates, as above described, gives a substantial, easy-running, and durable axial support to the belt-rollers, so that the belt travels smoothly to allow the best effect of the water on the ores, however the belt may be inclined or adjusted; hence the machine is adapted to a wide range of work in separating different classes of ores.

A greater or less number of the shifting water-boxes may be used than the three shown,

as may be preferred.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an ore-separator, the combination, with the endless ore-receiving belt F and the rollersD E, of the boxes B O, the bearings B 0, provided with studs 1) c and end lips, b 0 and the machine-frame, substantially as herein set forth.
